MACHINE yron APPLYING BOX 'sfranls` To all whom t may Concern.'

Be it known that I, ARTHUR Gr. G. `GrUnN- Irina, a citizen ofthe UnitedvStates, residingrat Chicago, in the county of Cook, State of Illinois,have invented van Improvement in a Machinefor Applying Box Straps, ofwhich the vfollowing `is "a specification.

This invention relates to Vmeans"forfacilitating the'application oftensional bindings to boxes and packages -and particularly tovastrappingbench, wherebyV tensional box .strapping may be applied, 'forreinforcing purposes to such-boxes and packages.

It is the object of the invention to yproduce a construction of "theCharacter described, simple and 'economical in construction and'efficient in operation. Other objects and 'advantages of "the inventionwill appear as thedescription tofolllon7 proceeds.

Fig. 1 isa plan view of the strapping bench.

Fig. is a 'sectional elevation thereof on the line 2-2 of Fig. 1

Upon reference to the drawings it will be observed that there isprovided, first, a platforni l equipped with rollers?, along which boxor package may be trundled; and 'that located about midway 'of theplatform l and at the rear side thereof is a reel 2a for box strapping3. Referring' to Fig. 2, (and assuminof a box to be in the positionindicated in dotted lines), the strapping 3 is fed "endwise from thereel, down the rear leg 4 of a collapsible U-shaped chan-nel iron strapguide. The rear leg 4 of this guide passes down below the plane of therollers and then forwardly as indicated at 5, while the front leg 6 hasa horizontally and rearwardly directed lower' end 7, which is telescopedwithin the forwardly extending portion 5 of the rear legy4, justreferred to.

This construction affords a collapsible U` shaped guide, of channel formin cross section, which guides 'the strapping fed endwise thereinto,down Vthe rear side of the box or package, under the bottom thereof andup the `front side, whereupon it can be overlapped, stretched, vandsealed on 'the top ofthe box by the operator.

It is desirable to compress certain types r of boxes and packagesduring` the application of tensional binders thereto. 'It is eiIicientto applythe compression `at the point where :the binder is put on. 'Iprovide a treadle 8, which by suitable connections",

. application med April 5, 1920. serial No. 371,264.

hereinafter more specifically described,'niay be depressed to vforcethefr'ear leg 4 offtlie collapsible AU-shaped 'strap guide forwardly.squeef/Jing` the box betweenthe twfolegs df the lguide, thus applyingcompression 'iipon the box at precisely the point where lit fisdesiredto apply the strapping.

Having pointed out brieiiy the'nio're importantoperating elements 4 ofthe machine, I lshall now describe the construction 'inde'- tail. e

The platform l is formed of `ang'le"iron 9 and channel iron l0 (Fig. 2)and'isrigidly supported upon the legs 1l. In the l,fr-nt and 'rear framemembers lof vthis-'plat'forin are mounted the rollers 2 fin anylsuitable manner, as by havingftheir yaxles seated in half bearings notshown. y i The front leg;F 6 of the collapsible `U shaped 'strap guideis firmly 'mounted lipn the front frame 'member 10j, a'braee 12'beingsecured upon that member-'for rigidity. The rear leg 4 of the Ushapedstrap guide 4is secured in a casting 13 Awhiohfis .inturn ,secured to anangle plalte v14, yfreno,whicl'i depend at a substantial vdistance fromeach other the two carriages 16, each of which isv ap'ertured toreceive, and slides on 'the rods 17, which are bolted as findi'cate'd 18across the platform, parallel to,betwee"n and below the plane of theriiillers.Vrv It 'has been pointed out that the U-shaped stap guide iscollapsible, the horizontal 'parts 5,-7 thereof being telescoped.I Itwill bel cle`arthat`tlie rear leg 4 thereof being slidable `along therods 17 may be brought forward or retracted in the .plane of a binderand at right arigles to the travel 'of the box as itA lis'trundledthrough the machine. Y .n The tread'le 8 through which the rear strapguide 4 is rno'ved forwardly swings 'on the pivot 2O havingbearings in abracket fili, secured to the rear angle iron -9,"the cur`ved arms 21.connecting the treafdl'f''y with its pivot.` Pivotally mounted on the"onrv'ed"y 17, ley-means 'of carriages e'anif the rear leg 4 of theU-shaped strap guide,

it will be apparent that pressing downwardk strap guide.

Means are provided Jfor holdingv the rear leg 4 of the strap guidenormally back in the position shown in Fig. 2 and thus to permit thefree passage of the box or package through the machine. Thus a long leafspring 30 is slidably secured at either end to the rear legs 1l ofthemachine, and clamped .at its kcentral portion'by means of thebolt 31 inthe hook 32,l on the bracket 33, which at its yrear end extends upwardlyand is secured to the angle iron 9' forming the rear' frame work of theplatform. This spring clearly serves normally to hold the rear leg ofthe U-shaped guide in its retracted position. f y

Forsupporting the` reel 2, I provide a stand 34, suitably secured to therear frame angle iron 9, from whichextends upwardly a support 35carrying an upper table .36, across which the strapv passes from thereel 2 tothe box or package,` and upon which it may be inspected. Thetable 36 is provided with spaced apertures through which are dropped thelegs of al heavy staple-like member 37 which thus rests upon the strapand serves to tension and steady its feed.

yIn operation, a box or package is trundled along the platform until theportion of it to which it is desired to apply the binder is .locatedbetween the front and rear legs ofk the U-shaped strap guide. Thereuponthe treadle is depressed and the box or package o heavily squeezedbetween the front and rear channel members of the U-shaped guide,

the strapping is'then drawn olii1 from thev reel and pushed downwardlyin the-,channel of the rear leg 4 ofthe strap guide, the U-shapedstrapguide directs the strapping down around the bottom of the box or packageand up the front side thereof where it may be overlapped, stretched andljoined. After this the strapping is broken off, the treadle 8 ispermitted to rise, releasing the box or package, which is then trundledalong the platform. It will be apparent that boxes having a wide varietyof girths may be handled on the same machine, and

f that the pressure applied to compress the box is under the control ofthe operator. Thus if desired the strap guide may merely be closed upona box or package in order accurately to direct the strap thereabout,without the application of substantial pressure thereto. The fact thatthe guide functions with equal eiriciency upon boxes and` packages ofwidely varying girths is equivalent to adjustability in theguide, butdoes not require an adjustment (in the proper sense) of the machine. Inthis sense the however is easily effected to cause the strap guide tofunction efficiently on boxes or packages of any size, from the largest`the machine will take, to those of very small size. This yadjustment maybe effectedby; shortening the rope 24, by knotting it further from oneof its free ends as is shown at 24'; (Fig. 2) which will leave the partsin the 'same position but elevate the treadle' and thus give the` guidea greater throw i. e., permit its rear leg to be moved further forwardupon the maximum depression of the treadle.- l Having described myinvention, I claim: l.
